One problem is that many players don't actually show the number of Kings in response to 5N (or the equivalent 'K' ask in other forms of keycard): they (including me) usually play 'specific King' responses, and this makes your scheme a bit difficult to implement.
And even if you play number of Kings, I truly think that you are underestimating the risk that partner will be left guessing.
Give him a side suit of, say, AQJx and the 'attached queen' of which you are so fond may be one trick, but the side suit K is, essentially, two extra tricks.. and he won't know which it is. Of course, if you show an impossible number of kings, the problem goes away, but we don't normally have that luxury.
The problem hand you suggested, of Axx KQxx Ax Axx: well, let me suggest that this is amongst the easiest 7 bids of all time.
Admittedly, this is based on an imp approach, where I would expect 5N to ALWAYS show interest in grand. In mps, one could argue that responder will sometimes be interested in knowing whether to risk 6N rather than, here, 6♦. But at imps, safety first prevails in choice of denomination for slams.
And if I held a 7 control 17 count, with my side queen firmly stuck to K and length, I am bidding 7... mean... if he is waiting for me to hold an AKQxx suit before I jump to 7, then he is overusing 5N.
Put another way: I would have been very tempted to upgrade this to an 18 count if I held the 3=4=2=4 hand you suggest. Tempted: heck, unless all my x's were tiny cards, I would do it.
